Diabetics using a glucose monitor made by DexCom will be able to see a continuous graph of their blood sugar levels on the Apple Watch, says the company. It is working on an app for the smartwatch that is expected to be available when the Apple Watch launches in April – alongside a similar app for the iPhone.

DexCom’s glucose monitor tracks a person’s blood-sugar levels continuously. The [app] converts that data into a simple graph that is just a glance at the wrist away.

The WSJ reports that the early availability of the app has been made possible thanks to the Food and Drug Administration taking a more hands-off approach as of last month. While medical hardware still requires FDA approval before it can be sold, companion apps no longer need prior approval – developers simply have to notify the FDA that the app exists … Read more

Following Apple employees’ meeting with the FDA to discuss “mobile medical applications” earlier this year, AppleToolbox has published a response from the FDA to a Freedom of Information Act Request asking for more information about what was discussed.

A response to the request took three months to complete, and arrived just after Apple introduced its new HealthKit platform and Health app for iOS 8 last week. While much the FDA’s answer sounds like Apple was discussing HealthKit, the response also gives some interesting clues that Apple is working on health products that go beyond the sensors currently in the iPhone and iPad:

With the potential for more sensors on mobile devices, Apple believes there is the opportunity to do more with devices, and that there may be a moral obligation to do more… Sensors already exist on medical devices. For instance, Apple’s devices have cameras and accelerometers. There is still an opportunity to innovate, but Apple wants to make sure they are on the side of the FDA.

Readings are done with your hands in a comfortable position, and the health tracker was able to return our vital signs as well as a fancy ECG graph of our heart in just a few seconds. Out of the box, you’ll be able to pair it with your Wi-Fi scale and fitness tracker, so you can keep an overall picture of your health in the same place … Read more

Since our initial report, some more speculation and mockups have emerged online about the app. Above are a pair of mockups posted to Behance earlier today. The mockups follow some of the details presented in our original article:

The “Healthbook” application is said to take multiple user interface cues from Apple’s own Passbook app, which is software for storing loyalty cards, coupons, and other materials normally stored in physical wallets.

The new health and fitness application’s interface is a stack of cards that can be easily swiped between. Each card represents a different fitness or health data point. The prototype logo for “Healthbook” is similar to Passbook’s icon, but it is adorned with graphics representing vital signs.

According to sources, the mockups are “vaguely” the right idea. Of course, Apple is likely testing multiple different user-interfaces for this software, and since we are several months out from an official introduction, things can and likely will change (even drastically)…
